Remote Starter Avital

I recently bought an Avital replacement remote.
It's a 3 button, i believe 6 channel remote.

EZSDEI476 RPN 820031

I can't seem to find any instructions on how to program it.
I've successfully programmed it to turn on the car an open the doors,
but when I use the remote start feature, my lights constantly blink.

I'm guessing I'm on the wrong channel?
My guess the car alarm channel.

Can anyone help me out?

Anything is much appreciated

There is no being on the wrong channel. You need to look and see which brain you have and look up the programming guide for that. Let me know if you need help
